1.4 Long engine storage – Inactivity
If the engine remains inactive for a period of time exceeding 6 months, you need to protect it from oxidation and
breakdowns in accordance with the following instructions:
1 Let the engine run for 15 minutes at 800 rpm; stop the engine and drain the oil.
2 Put oil (according to the specifications MIL-60B-type 2) into the oil sump until the oil sump reaches at least
‘Min’ on the oil dipstick.
3 After emptying the fuel filters, disconnect the pipes of the feeding of the injection system at the top of the
feeding pump, and connect it with the proper tank containing oil CFB (ISO 4113).
4 Let the engine run for 15 min. at 800 rpm; then, by using an oil gun, slowly atomize (nebulize) for about one
minute 60 grams of oil MIL-60B-type-2 into the intake manifold.
5 Disconnect the pipes of the feeding of the injection system from the tank containing the oil CFB and re-
connect it to the fuel tank.
6 Seal with tape, on both the engine and exhaust pipe, the access lights, aeration lights and breather pipe
lights.
7 Put a very visible paper on the engine where it is clearly stated that the engine is ‘WITHOUT OIL’.
8 Disconnect the batteries and put them in a dry place, always making sure that they are charged.
9 Drain the cooling water in case it does not have anti-freezing liquid or anti-corrosion liquid
10 If the engine is connected with the propulsion system verify for the oil level.
11 Clean the engine from salt and eventual rust. Paint rusted parts. Spray the engine with CRC 6-66 marine
lubricant spray to avoid corrosion.
After a period of inactivity, it is necessary to carry out a some maintenance work before starting the
engine again to ensure its efficiency conditions.
1 Check the battery charge level conditions. Assure that the battery voltage is over 12.5 V.
2 Make sure the electric contacts are intact. Assure the correct electrical connections.
3 Carry out the engine diagnosis.
4 Check the oil level-conditions, and if necessary, top- up or replace.
5 Verify and if necessary replace the oil filter.
6 Check the coolant level an mixture, and if necessary top – up.
7 Replace / Clean the fuel filter.
8 Clean the air filter.
9 Verify the belts status and tighteners.
10 Verify the integrity of the sea water pump impeller.
